IMPROVED BRICKfM'AGHINB.

TO ALL 'WHOM IT MAY-CONOERN:

Be it known that I, SMUEL J. PARKER, of Ithaca, Tompkins county, New. York, have invented an Improved Brickl\'lachine;.and I do hereby declare that the following is a full and exact description thereof, reference being had to thcannexed drawings, and to the letters thereon'. v

Figure 1 is a side elevation of my machine, adjusted for first quality brick.

Figure 2, a view of the feed-plate for my rst quality brick.

Figure 3, the cam-plate.

Figure 4, a view of my feed-plate for the second quality of brick; and

Figure 5, my feed-plate for my third `quality of brick.

My object is to make a simple and durable machine, ready adjustable for making three varieties of brick: first, a hard-pressed, finely-finished brick; second, a brick worked with more moisture of the clay, and pressed, as far as convenient, for that degree of moisture; and third, a brick Worked quite moist.

For these purposes, I use one general arrangement, and several lesser devices that I shall describe.

In tig. 1, A is the mould-wheel, made with one, two, three, or more moulds, the size, flatwise, of a brick, but somewhat thicker than the brick, that it may be dressed oit', and made true as it wears; and B are one, two, or more plungers, that play in the moulds; and C is the xed cam, adjustable by the set-screws D, that gives motion to the plungers in the moulds; and E is the stationary feed-plate, adjustable by the set-screws F to the mould-wheelA, and having the feed-entrance or pipe G, through which the clay enters themoulds as the wheel A revolves, and the delivery-shelf H attached to it. The feed-pipe is made less in size than the face ofthe brick towards the feed-pipe or entrance. This is so made because clay, at a right tension or plasticity and pressure, moulds smoothly against a metallic surface, but is roughened easily where cut off from the clay at the feed-pipe. Thus I designedly contract my feed-pipe as much as possible, and cut of(` by the motion of the wheel as little as I can cf'lclay from clay. The delivery-shelf` is also peculiar, in that it is made by such a curve on its upper edge, at I, as to just clear the emerging brick, yet be certain to catch it, when the pitman or plunger of the mould pushes it out of the mould. The delivery-shelf` is also `cut away slightly, a quarter or a half of an inch, next tothe mould-wheel, in the full-sized machine, so that, for an instant, the plunger comes out of the mould beyond the front of the face of the mould-wheel A, and recedes again while the mould-wheel is moving. This is represented at B a, and is for the purpose of leaving thc brick on the shelf sofar clear of the mouldwheel that the opera-tor can brick on the shelf, and the better remove them to the reeeivin mould-wheel shall then detach the brick the better from thei shelf. The wheel A is supported and revolves on the shaft L and at K. On it are put the horizontal screw-arms or other revolving appliances that press the clay from a stout chamber into the feed-pipeG. The whole is held by the bed-piece M, and at N is seen the removable additional cam on the surface of the cam C.

By the arrangement just described my first quality of bricks is made,

dry as can be conveniently worked, enters the mould by as small a feed-pip as A revolves, the clay fills the mould, and as th g-hoards; and also'that the onward motion ofthe and the process is that the clay, as

e mould moves on, the feed-plate cuts otl the supply of clay from the mould, until the filled mould arrives opposite a perfectly smooth metallic part of the feed-plato at R, g. 2, when at this instant the friction-roller, on the end of the plunger tubes B, meets the removable addi tional cam N,Vwhich suliiciently compresses it when surrounded on all sides by smooth metal,

and leaves a very finished impress on the brick. Then the wheel, passing the cam N, revolves on,

and the rollers on B reach the as at Bl a, beyond the face of the mould-wheel, and thus the brick out on the sheli', as has been described. Inig. 2 is seen the first-,quality brick'teed-platc removed. The red lines show the three moulds i-n the mould-wheel A in one of their positions, R being pressed put a thin spatula of wood or a steel trowel in between the mould-wheel and""thc1 r adhesion to the plunger, and leave them on ther e as'can be conveniently used; and' by the additional cam N, and U just about tobc lled, and Vjust about to be emptied on the shelf` H, fig. 1,'

as has vbeen described. In iig. 3 is seen the cam-plate C removed, and A is the outlin N theremovable additional pressure cam,

e ofthe mould-wheel, and and T the delivery part ofthe cam C. In iig. 4 is seen thedplate for the medium or second quality of brick. It is adjustable iii the place of E to the machine. When at W, on the shaft L, is fixed a cog-wheel, which meshes into another oog-wheel on the shaft of the wheel X, and moves the substantially as shown and described;

latter twice as fast as the mould-Wheel A. The effect is, as the moulds in A are tilled through round feed-pipe G, the Wheel X cuts olf the clay as by a smooth-edged saw-plate or revolving knife-edge, and after it is eut otf, smooths the surface. next -to X as by a troweling motion.

Thus the opera-tion ofthe machine is precisely as has been described, except that there is no cam N used, but only the cutting and smoothing of the cutter X in rnaking this quality of brick. In iig. 5 the feedplate EW difl'crs from the plates E and E in that no cam N is used nor cutter X, but an additional feed-pipe, Z, with lateral grooves, is used. The effect is that a thin clay plasters or smooths over the cut surface of the clay from clay which takes place as the clay enters and parts from G. And thus by this arrangement I use a thinner clay but obtain a less smooth brick. I also use other arrangements and combinations of the ldescribed parts of my brick-machine, but they, as well as'the advantages and uses of my invention, are apparent to those skilled in the art to which they appertain.
